emulators/wine-mono-devel: Update to version 7.0.0

This includes the following changes:

• SEH exceptions in Marshal.Release are now silently ignored. This fixes a crash in the launcher of Borderlands GOTY Enhanced.
• The Interaction.Command method has been fixed to return only command line arguments, not the program name.
• Implemented special marshaling behavior for IsCopyConstructed. This fixes a crash in SteamLayerWrap.dll on x86.
• Updated Mono from upstream.
